Installation & Safety Instructions
- Disconnect DC main‑power supply before fuse installation or replacement to avoid short‑circuit hazard.
- Apply proper tightening torque for 8.8‑grade screw; insufficient torque will trigger abnormal over‑heating under heavy‑current load.
- Select ANL‑B series medium fork‑bolt fuse according to actual continuous working‑current of the circuit.
- Perform temperature derating assessment when installing inside sealed high‑temperature compartments.
- Regularly inspect screw‑nut tightness for vehicle and vibration‑intensive working environments.
- Confirm official dimension drawing before bulk purchase since dimensions may change without prior notice.
